这几天使用C#操作windows帐户相当纠结，以前没做过，google翻阅了不少资料，尝试不少方法，终于解决了我的问题。

1.创建windows帐户

view sourceprint?01 /// <summary> 

02 /// 创建Windows帐户 

03 /// </summary> 

04 /// <param name="pathname"></param> 

05 /// <returns></returns> 

06 public static void CreateLocalUser(string username, string password, string description) 

07 { 

08     DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer"); 

09     var newUser = localMachine.Children.Add(username, "user"); 

10     newUser.Invoke("SetPassword", new object[] { password }); 

11     newUser.Invoke("Put", new object[] { "Description", description }); 

12     newUser.CommitChanges(); 

13     localMachine.Close(); 

14     newUser.Close(); 

15 }

2.更改Windows帐户密码

view sourceprint?01 /// <summary> 

02 /// 更改Windows帐户密码 

03 /// </summary> 

04 /// <param name="username"></param> 

05 /// <param name="oldPwd"></param> 

06 /// <param name="newPwd"></param> 

07 public static void ChangeWinUserPasswd(string username, string oldPwd, string newPwd) 

08 { 

09     DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer"); 

10     DirectoryEntry user = localMachine.Children.Find(username, "user"); 

11     object[] password = new object[] { oldPwd, newPwd }; 

12     object ret = user.Invoke("ChangePassword", password); 

13     user.CommitChanges(); 

14     localMachine.Close(); 

15     user.Close(); 

16 }

3.判断Windows用户是否存在

view sourceprint?01 /// <summary> 

02 /// 判断Windows用户是否存在 

03 /// </summary> 

04 /// <param name="username"></param> 

05 /// <returns></returns> 

06 public static bool ExistWinUser(string username) 

07 { 

08     try

09     { 

10         using (DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer")) 

11         { 

12             var user = localMachine.Children.Find(username, "user"); 

13             return user != null; 

14         } 

15     } 

16     catch

17     { 

18         return false; 

19     } 

20 }
4.删除Windows用户view sourceprint?01 /// <summary>
